Involved excavation of 6000 cubic metres of material for a retention basin at the C.H.P.P, as well as the construction of the basin, Oldknow Earthmoving and Haulage (OEH) were required to re-shape the surrounding areas to allow surface water to enter the basin. This included the lengthening of an existing 600mm R.C.P to a containment sump and continuing into the basin, the removal of material to allow excess water to flow from the rotary breaker area to the basin and R.C.P installation to allow overflow water from an existing sump to enter the basin.
